Abstract
A circumaural earphone including a headband, an adjustment mechanism, a rod, and an earphone module assembled to the rod is provided. The adjustment mechanism disposed at an end of the headband includes a housing and a pivoting ring assembled in the housing to be rotatable about an axis relative to the housing. The rod is disposed rotatably through the pivoting ring and the housing along the axis, wherein the rod and the pivoting ring are adapted to each other structurally for the rod to drive the pivoting ring to rotate about the axis synchronously. The earphone module is disposed on the rod.
Claims11
A circumaural earphone, comprising:
- a headband;
- an adjustment mechanism disposed at an end of the headband and comprising:
- a housing;
- a pivoting ring assembled in the housing to be rotatable about an axis;
- a rod disposed through the pivoting ring and the housing to be slidable along and rotatable about the axis, wherein the rod and the pivoting ring are adapted to each other structurally for the rod to drive the pivoting ring to rotate about the axis synchronously;
- and
- an earphone module assembled to the rod,
- wherein an inner surface of the pivoting ring has a first adapter portion and an outer surface of the rod has a second adapter portion, wherein when the rod is disposed through the pivoting ring, the first adapter portion and the second adapter portion are closely in contact with each other without a gap, and the first adapter portion and the second adapter portion are movable relative to each other along the axis without being blocked, and the first adapter portion and the second adapter portion interfere with each other in a rotation direction about the axis,
- wherein the rod contacts the inner surface of the pivoting ring when the rod slides along the axis, and an outer surface of the pivoting ring contacts the housing when the rod rotates about the axis.
